Application filed September 29; ism." seflai No. 792,281.

To all whom it may concern: I

.Be it' known that I, OBIN m a citizen of the United States; residing" at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Tire-Protectors, of which the following is a specification. This invention relates to pneumatic tires for automobiles, and has to do more partic- I, ularly with a protective means for the-inner tubes of said tires, the principal object of 'the'invention being to provide an eflibeen worn down through service till the inner fabric portion 3 is on the surface. I

a line 2-2 of Fig. 1. Fig. 3 is a cross section of an outer casing. showing the location of the said protector within thesame.

Describing now more particularly the device and the process of obtaining the same,

and referring to the numerals of reference on the drawings, 1 representsan outer casin comprising the treadportion 2, inner fa ri'c layer 3, and bead or clencher memhers 4. 1 c

To obtain and manufacture one of my imapes a ta -tam may be obtaliied for proved protectors in the most economical then cut the bead members 4 off around the entire periphery at a point as indicated by 5, and turn off all rubber which may still re- 'main on the fabric member, thus producing manner, I obtain an outer casin which has i a substantial yet sufliciently flexible endless liner or protector such as 6. ,I have found that by this process andafter removing the bead portions 4, the remaining member 6 shrinks sufliciently to allow it to be placed within a casing of the same size as said protector was originally-constructed, thus.

forming an efiicient protection for the inner tube against blowouts or punctures. As these wornout casings as such areireadily obtainable at a low cost, and as the product obtained therefrom is better by reason of its having stretched its limit, it will be seen that I have thus provided a protective means for inner tubes of greater elliciency than if the protector were constructed from new material at a much greater cost.

Iclaimi- The combination with a tire comprising an outer casing and a pneumaticinner tube of an annular liner removabiy seated there between and consisting of-the continuous,

service-stretched fabric portion of 'a used outer casing.

In testimony whereof I atfix my signature in presence of two witnesses.
